printing at home from digital camera
I have a D1x and my wife wants to start printing some of these at home with our HP Photosmart printer. A couple of pretty basic questions from a neophite.
1. The resolution in photoshop usually shows 72 dpi, that's used for screen resolution but for printing you want at least 300 correct?
2. What resolution (in dpi) does the D1x store it's settings? I can't find this anywhere in the literature, or is this irrelevant to the camera?

300 should be plenty. You can go quite a bit lower and still get very nice images. I printed a shot from my D1 on 12"x18" paper a couple weeks ago at just over 100 dpi and it looked great.

I don't know what if the camera assigns a dpi with the file, but it doesn't matter. When you tell the printing program (Photoshop or QImage or whatever) what size on paper to make the print, the dpi is a function of that.

Your camera does not apply a dpi setting to images. Your image editing program does that (and 72 dpi is a typical "default" setting). Your D1X produces a 3008 x 1960 pixel image. This will be sufficient to print at very high quality up to 10 x 15 inches. All that really matters from a printing point of view is how many pixels you have to work with.
Here is what I would suggest. Uncheck the "resample image" box in Photoshop or whatever program you are using to edit and print images, and simply change the print size from whatever the defaults give you to whatever you would like. Keep the "constrain aspect ratio box checked". If you change the width of the image to 10" for example, then the vertical distance will automatically change to 6.5". The dpi box will now show something like 300.8 dpi. This is fine. Print.
When you resize for printing, all you really need to to is keep an eye on that dpi setting after you adjust the print size. As long as the dpi is 240 or above, your prints will be of excellent quality. From 180-240 dpi, your prints will generally be OK, but noticeably softer. Below 180 dpi, you might want to consider checking the "resample image" box and putting in 200-240 dpi to reduce pixelation.
I hope this makes sense. It's actually easier to do than describe.
